IMPROVEMENT IN METALLIC PACKINGS FOR OIL-WELL PUMP-VALVES.

Specification forming part of Letters Patent No. l87,762,dated February27, 1877; application filed November 17, 1876.

To all whom .tt may concern:

Be it known that 1, THOMAS BARNES KEL- LEY, of Harmonsburg, Crawfordcounty, Pennsylvania, have invented a new and Improved Mode of PackingValve-Chambers or Buckets for Oil-Pumps, which improvement is fully setforth in the following specification, reference being had to theaccompanying drawings:

The object of my invention is to construct a packing for valve-chambersor cylinders or buckets of oil-Well pumps, of metal, that will adjustitself to the inside of the pump-barrel.

Figure 1 represents a valve-cylinder or binget, with the packing inplace. (Shown at This packing -is composed of two metallic rings, cut insegments, as shown at 1 2 3 4, Fig. 2. Back of these segments is acircular spring, H K, that passes around the valve cylinder or bucket ina deep groove made therein, and in which the packing-rings are placed.This spring is left open at H, and

against it the segments of the packing-rings rest, and they are by itforced out against the pump-cylinder.

Fig. 3 is a sectional view of my packing.

On the inside of the packing-rings 1 2 3 4 are flanges O O 0 0, whichfit into a recess in the collars S T, and serve to keep the rings inplace.

When the rings are in place they are so adjusted as to break joints thatis, the solid part of the lower ring is opposite the opening in theupper. This makes a tight packing. (See Fig. 1, where F represents theopening between the ends of the segments 1, 2, and 3the solid part ofthe segment in the lower ring.)

I claim- The packing-rings D, constructed in segments 1 2 3 4, with theflange at O O O O, in combination with the spring H K, constructed asdescribed, for the purposes set forth.
